4. Virginia Commonwealth Rams

VCU is one of only three teams to make the Final Four with a No. 11 seed, as George Mason (2006) and LSU (1986) did so as well. No other teams have ever made the Final Four with worse than a No. 9 seed.

VCU, which was criticized by analysts for even making the tournament, has already proven those critics wrong.

The Rams can show the critics up even more by going to the title game.

Jamie Skeen led the Rams to their improbable 10-point win over the top-seeded Kansas Jayhawks.

VCU does not have any dominant players, but it is a very well-rounded team.

Teams, and the rest of the country, should not be taking the Rams lightly anymore.

2. Butler Bulldogs

When a team is a No. 8 seed and one of two Cinderellas left standing in the Final Four, that means the NCAA tournament has had a great few weeks.

The Butler Bulldogs advanced to their second straight Final Four, looking to avenge their championship-game loss last year.

Matt Howard may be one of the tournament's most underrated players. At the end of every game this tournament, Howard has had the ball in his hands and been the deciding factor in whether Butler advanced.

Shelvin Mack provides the team with steady offense and leadership as well. The duo of Mack and Howard combined to score 41 of the team's 74 points in Butler's win over Florida.
